A very nice, historical document, of course. However, I also find it fascinating that its 1983 perspective further confirms the impression that the field of computer science and technology has, at least conceptually speaking, been mostly stagnant since the mid-80s. Nothing that we have now that wasn't pretty accurately predicted 30 years ago. Nothing that we envision now that wasn't already envisioned in pretty much the same way 30 years ago. The only two developments I see as having had a profound practical impact in those three decades are parallel computing and the pervasiveness of global networking; and only the scale of the latter would have seemed hard to imagine back in 1983.
